求大神帮忙改一下我的中线提取程序
void zhongxiantiqu()
{
  unsigned char temp1,temp2;

   Blackleft[j]=Blackleft[j-1];
   Blackright[j]=Blackright[j-1];
   BlackCenter[j]=BlackCenter[j-1];


   for(i=ROW-15;i>=5;i--)
   {
   for(j=0;j<=60;j++)
      {
      if(Buffer[i][j]<THRESHOLD)
      {
         sum_left+=j;
         BlackCount_left++;

            if(BlackCount_left>=3)
            {
            temp1=(unsigned char)(sum_left/BlackCount_left);
            if((temp1-Blackleft[j]<10) && (temp-Blackleft[j]>-10))
            {
               Blackleft[j]=temp1;
            }
            }
      }

      }
      for(j=120;j>=60;j--)
      {
      if(Buffer[i][j]<THRESHOLD)
      {
         sum_right+=j;
         BlackCount_right++;

         if(BlackCount_right>=3)
         {
            temp2=(unsigned char)(sum_right/BlackCount_right);
            if((temp2-Blackright[j]<10)&&(temp-Blackright[j]>-10)) //与上场该位置进行比较，相差不大就更新
            {
            Blackright[j]=temp2;
            }
         }
      }
      }


      temp=(uchar)((Blackleft[j]+Blackright[j]) >> 1);
      if((temp-BlackCenter[j]<20)&&(temp-BlackCenter[j]>-20))
      {
      BlackCenter[j] = temp;
      black_lost=0; //黑线丢失计数清0
      }
   //Image_Filte();
}
